2. The greatest source of misery and hatred in this world is clinging to past hurts.Look at all the terrorists and militant groups that hark back to some event long gone, or base their justification for killing on claims of some supposed historical right to a bit of land, or redress for a wrong done hundreds of years ago.

　　2。这个世界上痛苦与仇恨最大源泉是对过去的执迷。
